Common mode voltage, also referred to as DC-offset, is unblanced power delivered to the motor by a VFD. Image credit: Eaton Corporation Capacitive discharge current The fast switching time of the IGBTs createsparasitic capacitance, which causes capacitive coupling between the stator and rotor. Th...
a在这种环境下,如何对房地产开发成本进行控制,使企业立于不败之地,已经成为每一个房地产企业必须面对的重要问题 Under this kind of environment, how carries on the control to the property development cost, causes the enterprise to be in an impregnable position, already became the important question ...
If you look closely at the section doing a couple of pads at once you will see that he doesn't just move the iron away from the pads. There is a quick jerk away from the pads. This causes the surface tension of the solder on the iron to pull the excess solder from the pad/lead...
Similarly, a variable frequency drive reduces inrush current by controlling the voltage supplied to the motor. But a VFD works by varying the frequency of the voltage, rather than the amount of voltage, to the motor. You may also like: What are thermal overload relays and what motion comp...
In a Kando system, a single overhead line carries the single-phase supply of 16KV, 50Hz. This high voltage is stepped down and converted to three-phase supply of same frequency in the locomotive itself through the transformer andconverters. ...
